This invention relates to an improvement in car-couplers; and itconsists in certain peculiarities-of the construction and arrangementvof the sanie, substantially as will be hereinafter more fully set forthand claimed.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich'- Figure 1 is a longitudinal vertical section of two freight'earswith my coupler in use,'and Figs. 2 and 3 are end'elevations ofeone ofthese cars, showing the vcoupler in two different positions.

a represents the body of a car, made in any suitable and usual way,and ais the draw-bar provided with the usualspringcz. This drawbar is at itsforward end confined in a vertical frame, a3, so as to be capable ofaslight vertical play, and-a spring, a, is placed over-it to hold itdown to the proper position.

Upon the forward end of the bar a is formed a nose, b, which is allowedlto project both yabove, and below' the bar, and is beveled off on itsforward end in bot-h directions, as shown. Just in rear of this noseeach draw-bar is formed with a hole'or opening, b', and by reference'toFig. l it will be'noted that as two cars are brought together thebeveled noses of the opposing drawheads cause them to pass over eachother and .drop together, as shown, Y

interlocking with the projecting portion of each, engagedk with theopening of the other.
